Webmail Super Slow on One

Hi,
Lately I have noticed that the webmail on the One has been super slow, especially Roundcube (which is usually fast).

Is there anything that needs to be configured on my end to make this work faster? I’ve tried different browsers and different computers. As well as clearing cache/cookies.

Thanks for any help!

The One server is a bit older hardware. Let me try popping the LiteSpeed server on there to see if that helps. If you don’t see an improvement in the next few hours, please let me know.
